The Allay is a small, blue, levitating mob that you can befriend in your Minecraft world. The two things he loves above all else are music and items he can hold in his hands. The Allay can be especially helpful to you when you want to farm a certain item. Once an Allay has joined you, more on that later, you can send him out to collect items for you. To do this, you can simply right-click on an item and give it to him. The Allay will then search for the same item in a radius of 32 blocks around you and bring it to you. For example, if you give it a cookie, it will bring you all the cookies lying around in this radius. He can’t mine blocks, but he will collect all items openly accessible. So you’ll never accidentally leave anything lying around again.

As already mentioned, music is the Allay’s second great passion. This means not only that you can dance exuberantly with him, but also that you can use music to coordinate his collecting activity. You can place a note block and activate it so that the Allay puts the collected items there.
